Tenancy in cloud computing refers to the sharing of computing resources in a private or public environment that is isolated from other users and kept secret. Tenancy in SaaS is divided into two types: single-tenant SaaS and multi-tenant SaaS.
What is a Single-Tenant Architecture
A single-tenant cloud runs on a dedicated infrastructure. This means that the hardware, storage, and network are dedicated to a single client, and there are no neighbors to share hosted resources with. They may reside in a dedicated offsite data center or with a managed private cloud provider.
In a single-tenancy architecture, each tenant gets their own database. This way, data from each tenant remains separated from the other. Furthermore, the architecture is built such that only one software instance per SaaS server is allowed.
Advantages single-tenant cloud
- Enhanced security - Single-tenancy offers true data isolation that contributes to optimal protection and increased security.
- Migration- When a tenant wants to migrate from a single-tenant (SaaS) system into a self-hosted or local environment, they can quickly move an application to their own managed servers.
- Customization- Single tenancy offers the ability to architect an environment exactly how a consumer needs it.
- Reliability- Single tenancy offers consistency and the highest level of performance for an application.
Drawbacks of single-tenant cloud
- Cost: Because, single-tenant does not allow cost-sharing for facilities such as deployment and monitoring, companies end up paying more. Also, more customizations and maintenance often take more resources and time, which results in higher costs.
- Maintenance: Since a single-tenant architecture needs continuous modifications and improvements, a lot of maintenance is required.
- Setup: There may be delays due to individual installs, and not to forget the learning curves, that should be considered as well.
What is a Multi-Tenant Architecture
Multi-tenant cloud architecture is a single cloud infrastructure built to serve multiple businesses. The entire system may cover multiple servers and data centers, incorporated into a single database.
Cloud providers offer multi-tenancy as a gateway to share the same application with multiple businesses, on the same hardware, in the same operating environment, and with the same storage mechanism.
Advantages of multi-tenant architecture
- Scalable: It is very easy to onboard users with a multi-tenant cloud. In fact, there is no difference between onboarding ten users from a thousand companies or a thousand users from one company.
- Saves money: Multi-tenancy allows resources to be consolidated and allocated efficiently, thereby saving a lot of expenses.
- Flexible: A multi-tenant cloud can allocate a pool of resources to the users who need it, as their needs scale up and down.
- Efficient: Multitenancy reduces the need to manage infrastructure and handle updates.
Drawbacks of multi-tenant cloud
- Security: Cybercriminals can take advantage of multiple access points to exploit systems vulnerabilities.
- Backup and restoration: A lot of companies fail to keep up with the latest system backup advances and restore options.
- Limited management: They do not provide a lot of customization options, and that reduces the consumer's ability to interact with the system.

Single-Tenant vs Multi-Tenant Cloud
What is a Single Tenant?
Single-tenant is an architecture in which one entity is supported by a single instance of a software application and supporting infrastructure.
Benefits of Single-Tenant Architecture
Security: It offers true data isolation that contributes to optimal protection and increased security
Backup: The tenant can manage updates by downloading and upgrading local applications.
Migration: When a tenant wants to migrate from a single-tenant (SaaS) system into a self-hosted or local environment, they can quickly move an application to their own managed servers.
Customization: It offers the ability to architect an environment exactly the way a tenant needs it.
Flexibility: It offers greater control over implementation and framework.
Limitations of a Single-Tenant Architecture
Cost: It does not allow cost-sharing for facilities such as deployment and monitoring.
Maintenance: It needs continuous modifications and improvements.
Setup: It is not always as convenient to install a single-tenant framework.
What is a Multi-Tenant?
Multi-tenant is a single cloud infrastructure built to serve multiple businesses.
Benefits of Multi-Tenant Architecture
Scalability: There is no difference between onboarding ten users from a thousand companies or a thousand users from one company.
Cost-effective: A cloud provider may sell its services to many customers at a much lower cost than each customer having a dedicated infrastructure.
Flexibility: It can allocate a pool of resources to the users who need it, as their demands scale up and down.
Efficiency: It reduces the need for individual users to manage infrastructure and handle updates and maintenance.
Shared data centers: A vendor doesn't have to create a new data center for every new user.
Limitations of a Multi-Tenant Architecture
Security: Cybercriminals can take advantage of multiple access points to exploit systems vulnerabilities.
Backup and restoration: Most multi-tenant platforms do not offer robust restoration options.
Limited management: They do not provide many customization options, which reduces the consumer's ability to interact with the system.
Single Tenancy vs Multi-Tenancy: Which Is The Right Solution?
Single tenancy offers high user engagement with environmental customizations, more security, and a better propensity for backup. But it costs much higher than its multi-tenant counterparts.
You need to decide what is important to your business and what you can afford to sacrifice.
